WP_User_Query PHP

Good day, I dabble with php here and there, but I’m stuck. I want to make the query only contain the subscriber role and not sure how to write it. I have this to pull all role, obviously the default.

// The Query
		$user_query = new WP_User_Query( $args );
	  	$total = $user_query->get_total();

Please let me know what I’m missing for the role filter and how to write it. Thanks.
